Code B1682 Ford Description

The B1682 Ford code indicates that the Passive Anti-Theft System (PATS) is disabled in the vehicle. PATS is a security feature designed to prevent unauthorized starting of the engine. When this code is triggered, it means that the system is not functioning properly, leaving the vehicle vulnerable to theft. PATS works by immobilizing the engine unless the correct key with the programmed chip is used to start the vehicle. When PATS is disabled, the engine may not start at all, or it may start but then immediately shut off.
